15 gal air compressor for priming engine bay


I am new to the forums. I read some articles and threads here and I am amazed with the information provided.

I have been reading for hours. Thanks everyone for sharing their knowledge.

I have a project car that I am working in my small garage. I am redoing the engine bay. I stripped it to bare metal replaced some panels, new wheel tubs, lots of welding etc.

Can I spray Epoxy primer, 2k high build primer and sealer with a 15 gallon air compressor ?

It says 5hp , 6cfm at 90psi on the compressor but I think those numbers are inflated.

I was thinking it is possible since the engine bay is fairly smaller surface than the exterior panels. And I can do it in sections.

My real concern is not to get water vapor in the gun. Any recommendations to prevent that ? Draining the tank, adding oil/water separator.

Would it help to let the air compressor cool down after it is filled ?

Any recommendations are appreciated.
